A Design of Secure Communication Architecture Applying Quantum Cryptography
Existing network cryptography systems are threatened by recent developments in quantum computing. For example, the Shor algorithm, which can be run on a quantum computer, is capable of overriding public key-based network cryptography systems in a short ...

Optimized Implementation and Analysis of CHAM in Quantum Computing
A quantum computer capable of running the Grover search algorithm, which reduces the complexity of brute-force attacks by a square root, has the potential to undermine the security strength of symmetric-key cryptography and hash functions.

QKD-Enhanced Cybersecurity Protocols
Security of QKD is guaranteed by the quantum mechanics laws rather than unproven assumptions employed in computational cryptography. Unfortunately, the secret-key rates are way too low and transmission distances are limited. The post-quantum cryptography

Trusted Noise in Continuous-Variable Quantum Key Distribution: a Threat and a Defense [PDF]
We address the role of the phase-insensitive trusted preparation and detection noise in the security of a continuous-variable quantum key distribution, considering the Gaussian protocols on the basis of coherent and squeezed states and studying them in ...

Lattice‐based cryptosystems in standardisation processes: A survey
The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives.

NTT and Inverse NTT Quantum Circuits in CRYSTALS-Kyber for Post-Quantum Security Evaluation
The emergence of quantum computers threatens current cryptographic systems, and NIST is preparing for the post-quantum era through the post-quantum cryptography (PQC) contest. CRYSTALS-Kyber is a lattice-based cipher suite that is used as a PQC standard.

Post-quantum Cryptography in 6G
The quantum computing paradigm is fundamentally different from the classical one. There are computational problems we are not able to solve on a contemporary computer, but which we can efficiently solve on a quantum one. One of these problems is the discrete logarithm problem (DLP) which is the basis of modern asymmetric cryptography.

Device-Independent Relativistic Quantum Bit Commitment [PDF]
We examine the possibility of device-independent relativistic quantum bit commitment. We note the potential threat of {\it location attacks}, in which the behaviour of untrusted devices used in relativistic quantum cryptography depends on their space ...
